I wouldn’t think that it would be available on the individual platforms like HBO Max or Disney+ or other such streaming platforms, as those are set up where you can watch whatever you want on the platform just by paying the monthly fee. This wouldn’t make much financial sense for MGM, EON, or Universal. Platforms like Amazon, where you would have to pay a fee to view the movie on top of the standard membership fee, are the direction that they would go. Apple would probably get in on it as well.
Comcast would also almost certainly carry it on their VOD platform that is available to their cable subscribers, as they own Universal. There are a lot of avenues that they could use to get the film out, but the subscription-based services like HBO Max and Disney+ and the like almost certainly won’t be the method of delivery.
